As Jenna Fischer's character on "The Office" gets ready to walk down the aisle with her Scranton love, Jim Halpert (played by John Krasinski), a new face is joining the cast as the mother of the bride.

"That's the rule we have stuck to on our show — it is supposed to be real average Joes, and casting a famous actor takes away from that," he told Ausiello. "We have only cast a famous actor when they can blend right in as was the case with Amy Ryan. Or if it makes sense for the role, like with Jack Black."

As previously reported on AccessHollywood.com, love is most definitely in the air for the stars of "The Office" – in addition to their upcoming on-screen wedding, both Jenna and John have recently gotten engaged to their respective partners off-screen as well.
